Product Name
Outsole Belt Flexing Tester GT-KB35

Product Introduction
The GT-KB35 outsole belt flexing tester evaluates resistance of outsole units and related shoe materials to crack initiation and growth under repeated flexing. The unit reproduces walking flex motion with an adjustable cycle count; the machine stops automatically at the preset number. Multiple specimens can be run simultaneously to increase throughput.

Application
Used to assess crack resistance of outsole components and other footwear materials subjected to repeated bending, applicable for quality control, incoming inspection and material R&D in footwear production.

Standards

• SATRA TM 133
• ISO 16177

Feature

• Simulates human walking flex to reproduce service conditions for soles.
• User-configurable cycle count with automatic stop at preset value.
• Capability to test up to 6 specimens simultaneously for improved efficiency.
